They've done this dance for a while, and with both seeing slowing subscriber rates, it's really no surprise.  I wonder what all the XM fanboys are going to say now?  I'm just happy I don't have to pay double for  my wife's "gift" of XM in her Honda,  and my Sirius subscription  in my car.   Pending shareholder approval, both companies expect the merger to be completed by end of this year.   Glad to see it- this is a situation where the consumer clearly wins.  More details at Orbitcast.
